Hexagonal Shelf

Requires 2 x 3.5mm diameter screws, the screw head diameter can be a maximum of 8mm, I included the project files so you can adjust these, I recommend using 5% infill but 20% on the bottom part of the screw holes for strength, and 15% on the top for high quality top layer and extra strength.

Printed on an Ender 3 S1 PRO with PLA, the size is made specifically to fit a 220x220 print bed.

The screw holes aren't threaded, I used drywall screws, 3.5mm diameter screws, the hole is 3.4mm so the screw is snug.

No special settings required, it's plenty strong to hold heavy stuff, I personally printed it at both 200C and 220C, bed at both 60C and 53C, printed it both slow and fast, both speeds yielded strong shelves, always printed it at 5% infill for most of the print, and 2-3 perimeters are enough.

I personally use glue for most wall mounted things for extra strength over time, the vibrations and forces can in time unscrew or loosen the holes in the wall, the glue will dampen the vibrations and prevent movement, I use some universal rubbery glue, I also used bathroom type silicone as glue, not needed but I highly recommend it.

Check the photos so you understand the infill areas that should be changed with a modifier box, you can search on youtube how to do it, you basically right click the STL in prusaslicer > add modifier > box; chance it's size accordingly and change the infill percentage.

I don't know who made the original design, I basically saw this type of shelves randomly in a store but they were hella expensive so I made my own in fusion360.
